Tooth cavity restoration with nanocomposite of epoxy resin and nanoparticles

A method of restoring a tooth cavity via a direct or indirect method with a visible light curable nanocomposite of a dental restorative material with a low polymerization shrinkage, wherein th dental restorative material comprises an epoxy resin, inorganic oxide nano particle, a photoinitiator and a photosensitizer;

• a) said direct method including the steps of:
• i) filling the light curable nano composite dental restorative material with a low polymerization shrink into the prior prepared tooth cavity;
• ii) stacking of the light curable nano composite dental restorative material with a low volvme polymerization shrinkage the tooth cavity;
• iii) applying curing visible light to initiate the polymerization process of the light curable nano comoos te dental restorative material with a low polymerization shrinkage;
• and
• iv) shaping and polishing of the light curablc nano composite dental restorative material with a low polymerzation shrinkage after the curing process;
• and
• b) said indirect method including the steps of:
• i) making a mold of the tooth after the cavity preparation;
• ii) casting of the mold with the light curable nano composite dental restorative material with low polymerization shrinkage;
• iii) applying curing visible light to initiate the polymerization process of the light curable nano composite dental restorative material with a low polymerization shrinkage;
• iv) shaping and polishing of the light curable nano composite dental restorative material with a low polymerization shrinkage after the curing process;
• and
• v) removing of shaped and polished nano composite dental restoarative material from the mold and adhering it to the tooth cavity of the patient.
